The Navier Stokes equations are differential equations that describe the flow of fluids with changes in density and temperature. They are used to describe weather or climate. They are non-linear, chaotic, with sensitive dependence on initial conditions.
That means, no finite description of a starting state, or any finite description of a number of starting states are sufficient to enable prediction of a long term future state.
This has been known since the 1963 paper by Edward Lorenz “Deterministic Aperiodic Flow”. It is a founding work in the study of chaos.
Having experience with clinical studies and controlled laboratory experimentation, I’ve always wondered how any advocate of anthropogenic global warming can even begin to make the claim that a sufficient number of climate data points have been collected with which to predict future trends. Apparently, plugging a few measurements into a supercomputer and running them through differential analysis is supposed to make up for the fact that there simply are not sufficient data points collected over a long enough period of time to even begin to derive appropriate equations for modeling long-term climate changes.
Models are dress-rehearsals at best. Any similarity to reality is either coincidental, temporary, or both.
